Tribocorrosion, involving both wear and corrosion in a systematic manner, occurs in a wide range of applications, including artificial hip and knee joints, food, pharmaceutical, transport and nuclear industries. A sensitive tribometer with the ability to conduct tribocorrosion measurements, in an environment with all necessary complementary analytical methods in an open-user facility, would allow this exceptional research team to detect these mechanically assisted interfacial corrosion processes. This instrument provides detailed information on the type of friction and wear. When coupled with a potentiostat, electrochemical signals can simultaneously be measured, providing information on disruption of the surface oxide and corrosion in conjunction with the coefficient of friction. Customized cells will be optimized for different research projects with unique requirements (e.g., oxygen content, temperature, absence of contamination for trace metal analysis). In order to perform certain types of tribological research such as the investigation of corrosion mechanisms in protein-rich environments involving friction, the wear and friction of advanced orthopaedic implant materials, and mechanically assisted interfacial corrosion processes for nuclear power environments and nuclear waste containers, the applicants require the use of an advanced and sensitive tribometer. A force resolution of 6 mN or better is needed for accurate information on subtle differences induced by these interfacial processes. The team of interdisciplinary (engineering, medicine, and science) and diverse applicants already have exceptional records of fundamental, medical, and industrial research activities, and the addition of an advanced tribometer will permit further advancement and collaboration of corrosion, tribology, and surface analysis researchers within Canada. The acquisition of a sensitive tribometer to Western will boost Canada's research reputation in tribocorrosion, and the device will be widely available to both academic and industrial users within Canada and internationally. To maximize access, the tribometer will be located in an open-user, low-vibration facility adjacent to complementary surface preparation and surface characterization equipment with active research staff scientists able to support HQP users and maintain the equipment. The team, instrument, training strategy, and facility have been carefully selected to facilitate the training and future, highly skilled, employment of HQP, including those from underrepresented groups.

摩擦腐蚀以系统的方式涉及磨损和腐蚀，发生在广泛的应用中，包括人工髋关节和膝关节、食品、制药、运输和核工业。在开放式用户设施中具有所有必要的补充分析方法的环境中，能够进行摩擦腐蚀测量的敏感摩擦计将使这个特殊的研究团队能够检测这些机械辅助界面腐蚀过程。该仪器提供有关摩擦和磨损类型的详细信息。当与恒电位仪耦合时，可以同时测量电化学信号，提供关于表面氧化物破坏和腐蚀以及摩擦系数的信息。定制电池将针对具有独特要求的不同研究项目进行优化（例如，氧含量、温度、不存在用于痕量金属分析的污染物）。为了进行某些类型的摩擦学研究，例如在涉及摩擦的富含蛋白质的环境中的腐蚀机制的研究、高级矫形植入材料的磨损和摩擦以及用于核电环境和核废料容器的机械辅助界面腐蚀过程，申请人需要使用先进且灵敏的摩擦计。需要6 mN或更高的力分辨率来获得这些界面过程引起的细微差异的准确信息。 跨学科（工程，医学和科学）和不同申请人的团队已经有了基础，医学和工业研究活动的特殊记录，并且增加了先进的摩擦计将允许加拿大腐蚀，摩擦学和表面分析研究人员的进一步发展和合作。Western收购敏感的摩擦计将提高加拿大在摩擦腐蚀方面的研究声誉，该设备将广泛提供给加拿大和国际上的学术和工业用户。 为了最大限度地利用，摩擦计将位于一个开放的用户，低振动设施附近的补充表面处理和表面表征设备与积极的研究人员科学家能够支持HQP用户和维护设备。团队、工具、培训策略和设施都经过精心挑选，以促进HQP的培训和未来的高技能就业，包括那些来自代表性不足的群体。
